I have written, in assembly language, a simple graphics package for a 400/600
which waits for commands to come in from the serial bus (which is really a
modified RS232 interface).  

I let the host computer simulate an Atari disk while the Atari powers up,
which allows the host computer to load a bootstrap program to the Atari.
This bootstrap is actually a graphics command handler, which "takes over" the
machine and monitors the serial bus for commands from the host.

I implemented a small set of graphics primitives (point draw, set draw color,
init screen, etc).  I think the higher level graphics stuff is best done on
the host side in higher level language.

If you know something about 6502 code you might be able to modify this to
do what you want.  If you are interested, call me at:
  
  615/574-5564 (tell secretary I said to forward the call or find me)
  615/691-7957 home, after 6PM EST

I am interested in your Atari--host Graphics and communication package.
What is the host machine that simulates the Atari disk?
